Chapter 3 covers the first form of reconstitution of a partnership firm — a change in the profit-sharing ratio (PSR) among the EXISTING partners. The same set of partners continues to carry on the business, but agrees that future profits will be shared in a different ratio. No partner enters; no partner leaves. The firm is reconstituted, not dissolved.
The chapter rests on two new tools: the Sacrificing Ratio (Old − New) which identifies the partners who give up a share of future profits, and the Gaining Ratio (New − Old) which identifies the partners who pick up extra share. The total amount sacrificed equals the total amount gained, so the sum of all partners' shares stays at 1.
Procedurally, four adjustments are made as on the date of change: (1) Revaluation A/c records changes in the values of assets and liabilities — gains on the credit side, losses on the debit side, transferred to old partners in OLD ratio; (2) accumulated profits, losses and reserves (General Reserve, P&L A/c, Workmen Compensation Reserve excess, Investment Fluctuation Fund excess, Deferred Revenue Expenditure) are distributed in OLD ratio; (3) goodwill is adjusted between sacrificing and gaining partners through their Capital A/cs — never raised in the books, because Accounting Standard 26 prohibits recognition of self-generated goodwill; and (4) capitals are adjusted to the new PSR proportion if so agreed. These adjustments form the heart of the 6-mark and 8-mark questions on the board paper.
